Description
Resolution:
The "received from" message trace log is generated after the message is received by EMS but before it is persisted to disk. When trying to diagnose a performance issue involving a message publisher, MSG trace alone is not sufficient if the latency is caused by a slow clock. You would need to track when is the response (confirmation of the publish) from the EMS server is sent to the client, by which time the message write has finished.
